I made a Mini Clueless Windoku X. The diagonals were a surprise for myself... I didn't discover them until I was making the clue set! But I was able to remove a lot of the clues once I figured it out.

Please, keep giving me suggestions on how to get the 9x9 Clueless Windoku put together. Just because there are 9 additional constraints! If it can be done with disjoint groups, I bet it can be done with the Windoku...

I don't know is a 4-clue is possible. Then you'd need one clue in each seperate puzzle because without clues a seperate puzzle is never unique.
I don't think there is enough interaction between the clues to make it possible.

Wow, I've made a quite few attempts and have hit places where I'm stuck or errors every time. I've only used pencil and paper so far.

How do other people print? I hit print screen, copied into Paint Shop Pro, cropped the background from my computer, printed. Would take advice on printing.

I guess I'll paste those strings into SudoCue one at a time (I answered my own question on that, finally). I'll call them Windex 1 through Windex 9, and then I'll make Windex A, B, C and D for the "pane" puzzles too.

I loved the way the full-length diagonals complete themselves, btw! A very complicated but interesting way they overlap and solve various sections!
